  When you look at the performance of a virtual machine, when you make a graphic of 3 months it appears correctly for the first two, but the last month is compressed.

  Hello

  When you say that the last two months are compressed. I do not have what exactly you mean by that. Is there a chance you can attach a screenshot of the same thing? Also let me know if there are any made VC-database activity recently?

• How can I pay for the reservation of memory on all virtual machines to "0"?

  I am trying to write a script that will pay for the reservation of memory on all virtual machines that are invited in a cluster to '0 '.  We have book too much memory, and this setting should allow VMWare facilities manage reserves memory for me.  I have hundreds of virtual machines to update, so I can't do it by hand.  I hope that it is possible via the CLI.

  Can someone help me with this please?

  Matt example work certainly, and I'm sure that he was going to follow up with something similar to this after having confirmed if it worked or not because it is much more serious on the optimization of code for speed, but I'll (try to) save the effort. To test its extract on a cluster of 45 VMS, it took more than four minutes to complete.  The excerpt below took about 25 seconds.  The difference is of course to use the cmdlet "Get-View" and that it can run asynchronously so (it begins a vCenter task and immediately passes the following).  Of course, this will also put more of a strain to your vCenter server, so keep that in mind.

  $spec = New-Object VMware.Vim.VirtualMachineConfigSpec
  $spec.memoryAllocation = New-Object VMware.Vim.ResourceAllocationInfo
  $spec.memoryAllocation.Reservation = 0
  Get-Cluster "YOUR_CLUSTER" | Get-VM | Get-View -Property Config.MemoryAllocation | %{$_.ReconfigVM_Task($spec)}
  

• is it possible to access the virtual machine when the network is down...

  Hello. He... IAM wondering is it possible that we can access the virtual machine when the network is down... (Because of power outages or when the fluctuations...) ................?

  Is it possible that I can configure my Virtual Machine...?

  Hello

  Not really...

  For an environment hosted... If you can access the console of the host, you can always access the console of the virtual machine regardless of the State of the network outside of the console. VMware Workstation, Fusion and server all fall into this category.

  For ESXi/ESX... you need a host outside to access the console of the virtual machine. ESX and ESXi not displayed graphics or VMs of their consoles and management devices. So, you need an external machine that can run the vSphere Client or access to the virtual machine via RDP, VNC according to Guest OS involved or SSH.

• Move a virtual machine to turn off between two hosts, shared storage

  Dear Experts,

  Please guide me for the next case. There are two hosts of Esxi, host 1 is Esxi 4.0 and host 2 is Esxi 4.1. There are store data SAN storage that is visible to both hosts.

  I watched solard winds VM monitor utility that hosting 2 consumes 90% of the memory while its processor is ok. On host 1 is normal. So, I want to spend only a few VM of to host 1. So please correct me if what I think are OK. I will turn off the virtual machine to be moved from host 2. Then I it will remove host 2 inventory. Then on host 1, I'll go to the data store in the folder that VM and do a right click on the file 'say add to the inventory' and now I'm going to see this virtual machine in the inventory of the host list, just turn on and everything is perfect, is this correct?

  Second question on the same hosts, there are a few other data stores that are visible to a host. As if this is the case there is a virtual machine on a data store that is visible to host 2 and I want to spend this VM to host 1 to reduce load on host 2. How to move this virtual machine because this data store is not visible to host 1? Will I have to copy this VM files in a data store that is visible to host 1? If YES then what real required to copy files?

  Kindly help me.

  Kind regards

  From your description I m assuming that you use not vCenter to manage your hosts, correct?

  If you have a store of data shared between two hosts you can do the steps you descripte (power off, remove the inventory etc.).

  For your second case there are several ways, it depends on where you want to place the virtual machine in the future. Wouldn't be on the shared data store that already exists or can in the local data store on the other host? Or is there an option to also display the current data store to host 1?

  If you want to copy the VM files copy the whole folder of it.

  Kind regards

• The virtual machine must be moved to another host?

  vCenter 4 runs on a virtual machine on vHost1. When you try to run an update for the virtual server that I have this message.

  The host has a VM VMware vCenter Update Manager or VMware installed vCenter vCenter. The virtual machine must be moved to another host for the remediation process to move forward.

  Before moving running virtual machine to a different host to vCenter, I thought I should ask if there is a better way to update vHost1?

  Thanks for your help. This is all quite new to me.

  Use VMotion to move your vCenter guest, you'll be fine.  Or if you have any DRS value fully automated when restore you one or more hosts DRS will move all of your guests.

• is it possible that an application on a virtual machine is faster than in its host?

  To measure the performance of our software on vmware, compare us the performance of vm compared to its host machine.

  We found that performance on three different machines showed a very different behavior, of 50% slower at 10% slower.

  And the strangest thing is that there is a single machine, his vm is faster than its host.

  Any help on the possible reasons is appreciated!

  Thank you!

  Additional information:

  The application is time CPU,.

  CentOS 6.2 for the vm and host,

  VMware Workstation 10.0.1 build-1379776

  Hardware Dell R720	VM vs host
  Xeon 2 CPU E5-2620 0 @ 2.00 GHz 12-Core, 32 GB	-50%
  Xeon 2 E5-2650 V2 2.60 GHz, 16 Core CPU, 32 GB	-10%
  Xeon 2 E5-2630 0 @ 2.30 GHz, 12 Core CPU, 64 GB	20%

  After eliminating the various factors, we finally understood the cause: hyper threading

  After that we switched off the hyper threading, everything became normal, the slower and faster virtual machines showed same performance.

  Host performance has even improved, about 10-20% faster than the virtual machine.

  Hope that this experience and this information can be useful for others in the future...

  Thanks for your help during our survey!

• Recommended Max vCPUs for a virtual machine

  Hi all

  A version of this question has been requested several times, but in the forums to search, I couldn't find this specific issue, so I hope I'm not duplicating discussions.  Here goes:

  I have a same ESX Server cluster.  These are HP DL380 G6, two quad core processors.  Here's what the processor properties appears under the configuration tab:

  Model Intel Xeon processor X 5660 @ 2.67 GHz

  2.7 GHz processor speed

  2 processor sockets

  By Socket 4 CPU cores

  16 logical processors

  Hyperthreading enabled

  I want to provide a virtual machine with 8 CPU.

  I understand that it is not advisable to set up a virtual machine with the same number of processors as the physical machine, in part because the Service Console needs a place to run and in part (or more) it will cause problems of planning.  My question is that when I say "the same number of processors as the physical machine", is that in this case 8 (or 16)?  Hyperthreading applies to this counselor?

  The only way you can provide 8 vCPU with a guest in vSphere4 should have undertaken more licenses.  If you do, I would say that to start with what applications/servers 'needs '.  Maybe 2vCPU and go up from there as performance requirements.

  If you have 16 logical processors and give comments 8, you aren't overcommiting, if it's the only host running on the ESXi host.  In addition, for ESXi, there is no Service Console.

• Cannot allocate more memory to the virtual machine image

  Hello

  I am currently using VMWare Workstation 5.5.4.  I have a Win XP image that I run.  My host computer has 4 GB of ram (3 GB recognized by hospitality Windows OS).

  Currently, I am only able to allocate a maximum of 1 372 MB to my virtual machine Image.  I want to allocate more memory to my image, as I do more memory intensive tasks to my image.  If I try to increase the amount of memory (even to 1376 MB), I get the following error message:

  

  Any ideas on how I can increase the amount of memory I can attribute to my image?  I use only 1 image currently.

  Loking at your vmware.log file, I see that you have a section "DEFAULT USER" including a "prefvmx.allVMMemoryLimit = line 1429". I believe that it is in conflict with the ' SITE HOST/DEFAULTS ' section which specifies "prefvmx.allVMMemoryLimit = 2297".

  The ' HOST/SITE DEFAULTS' config.ini is the traditional config.ini file that people recommend that you edit.  On XP, it should be located in C:\Documents and Settings\All Users\Application Data\VMware\VMware Workstation\config.ini

  I can't tell you exactly where the file config.ini 'DEFAULT USER' is located on Windows XP as I am running Vista.  I would start by looking under C:\Documents and Settings\\Application Data\VMware\VMware Workstation\config.ini to see if this file exists.  Or you can search your hard drive a config.ini file that contains the 'prefvmx.allVMMemoryLimit = 1429"line.

  I would recommend not not using the "DEFAULT USER" config.ini file at all.  In fact, on a default installation of Workstation 6.5 this config.ini file does exist.  I would recommend so transfer config.ini 'DEFAULT USER' settings to the "HOST/SITE DEFAULTS' config.ini and then delete the file config.ini 'DEFAULT USER '.

  After this is done, try again and let us know if things work better.

• ESXi host have not of virtual machines when connected through vCenter

  Hi all

  I am facing a problem with 1 ESXi hosts. All other hosts are working properly.

  All hosts are managed by vCenter 5.1 VM. When I select this problematic host in vCenter and click on the virtual computers tab, it does not display anything other than a blank page. Then, it throws an error saying that the object has been deleted or has not completely created. The screenshot of the error popup is attached.

  However, if I connect directly to the host through the VI client, it does not throw the error and I can see the virtual machines it. If I have vmotion the vms during this host, I do not see these virtual machines via vcenter but I connect directly to the host and I can see the virtual machines. They work very well.

  What could be the cause of this problem.

  Thank you

  AG

  I would try restart the management agent on the host troubled or removing of vCenter and time.

• Do not allow the virtual machine to power on if the host memory usage over 75%?

  Hi all

  I'm looking for a way to do not allow the power of virtual machines on if the clutser average memory usage is greater than 75%, or if its corresponding host memory usage is greater than 75%.

  Any idea.

  Thank you very much

  Hey Valot,.

  One way to achieve this is HA admission control that does not allow a virtual machine to be turned on if the availability constraints are not met

  Yes - you can
  but that will make your VM very slow

  set
  prefvmx.minVmMemPct = "50".

  or less - allowing you to approve the RAM
  Set this parameter in your config.ini file

• How to get memory for a virtual machine?

  In vSphere Client > select a virtual machine > summary under general tab, shows:

  Guest OS: Windows XP

  VM version: 7

  CPU: 1 vCPU

  Memory: 1024 MB

  General memory 103,58 MB

  With PowerCLI, how to recover this figure "103.58' for VM 'vm123 '?

  You can get the overhead of the memory of all your virtual machines with:

  Get - VM | Select Name,@{N="MemoryOverhead; E={$_. ExtensionData.Runtime.MemoryOverhead/1MB}}

• Unexpected shutdown of the virtual machine when compacting

  I have VMWare Server 1.08 on CentOS 5.3 with guests from Windows server 2003. the virtual machine uses 2 GB non-preallocated split files. I'm trying to shrink the virtual machine using VMWare tools. After him "are preparing to shrink" the process is over and I click "Shrink now" after a few minutes (this time varies a little) the virtual machine stops. I have a 2nd vm on this host as well and it stops as well. The host is a Dell 2900 with 2 processors quad core and 32 GB of ram and appx 1 TB of storage in raid 5. I checked memory usage and cpu during the process and memory, the cpu more than 100% for a short periods, but goes back down. Any idea what can be the cause?

  I'm not a person "linux", but am learning.

  I appreciate all help.

  Thank you

  If you get a lot of lines like that it usually means that either-

  -your physical disks are dead slow

  -the virtual disk has not shrunk Age

  - or is it close to corruption

  Some of these lines are not alarming per se - but if you see thousands of them like in your case that should sound the alarm.

  I'll try to use vmware-vdiskmanager with function r - and just clone the drive for growth in a preallouee.
